Bi 108 88 78 274


Y = [3(78) + 3(56)

- 274] / (3 1) (3 1)


 The value 32 is used in block III for treatment D.
For the analysis of variance, ANOVA (described in detail
later in this chapter), total degrees of freedom (d.f.) is
(rt 1) 1 = 7 and error degrees of freedom will be
[(r 1)(t -1)] 1 = 3. Treatment sum of squares when
calculated is reduced by [78 32(3 1)]2 / 3(3 1) =
32.67. Then treatment mean square and the F value can be
calculated.
